The end of the rectangular frame portion 4 and the transversely arranged reinforcing rib '8, serve to integrally unite the several overlapping web portions 5, 6 and 7 in proper spaced relation to provide a zigzag ventilation course through the floor casting 2, as indicated by the arrows in Fig. 4.

Rig-idly secured to the web portions 6 and 7 of the floor casting 2 is an automatic stereopticon projection apparatus C which cornprises a pair of vertically supported frame castings 9 and 10, on which an endless slide conveyor 11 is mounted to traverse the optical axis of a projector 12, also carried by the frame castings 9 and 10. A bracket 13 is formed integral with the frame casting 9 and serves to rigidly support an electric motor 14 and a gear box 15, which houses reduction gearing shaft 16 drivenfby the motor 13,and the driven gear elements 17 and 18 of a Geneva gear movement, which are connected through synchronizing clutch elements (not shown), to intermittently drive the slide conveyor 11. All of the parts 9 to 18 are specifically described and claimed in my co-pending application above referred to, and, therefore, need no special description except as such parts enter into new combinations, as will be understoodfom the fol-' lowing. v V V Adjustably'mounted, on the frame casting 9 is a bracket 19 having a shelf portion 20 on which an electric circuit flasher D is secured. The flasher D shown herein. is known as a mercury break flasher, but any other well known or approved flasher, ca-, pable of being continuously driven from the motor 14, could be substituted, provided it,

will operate to be described. Y

The mercury break flasher D comprises a pair of connected upright supports 21 and 22, bolted on the shelf 20 between which a series of spring pressed rocker arms 23 is journaled. A rotary shaft 24' journaled in the supports 21 and 22, carries a series of cam elements 25 which operate on the rocker arms 23 to alternately tilt a series of mercury circuit makers and breakers 26, adjustproduce the results later to ably mounted on said arms. A train of gears indicated as 27, 28 and 29 operatively connect the rotary shaft 24 with the motor driven reduction gearing shaft 16.

A series of electric circuit wires 30 connect the several mercury circuit makers and breakers 26 of the flasher D witha series of incandescent lamps 31, arranged around the marginal portion of a projection screen E.

The projector screen E, shown in Fig. 1, is constructed to represent the usual out-ofdoor sign board, around the marginal por- .tion of which, I have provided an endless series or border of incandescent electric lamps 31, connected through suitable electric circuit wires 30, enclosed in a conduit 32, with the automatic intermittently operated stereopticon apparatus C.

'In the operation of my improved stereopticonapparatus C, the electric motor 14 isconnected to intermittently drive a movable slidecarrier 11 to position successive slides into the opticalaxis of the projector 12, for projection on the screen or sign board E within the confines of the illuminated chaser border provided. by the series of incandescent lamps 31. The motor 14 is also connected by suitable gearing to continuously drive an electrieIcircuit'flasher D mounted ontheframe member 9 of the stereopticon apparatus C," which flasher is connected by suitable electric circuits 30 through an automatic master circuit controller F with the series or border of incan-i descent lamps 30 on the screen E, to flash alternate lamps of the series, in rotation, to produce a chaser or travelingborderaround the image simultaneously projected upon the screen.

In. the automatic operation of the come bined apparatus, amaster circuit controller,

such as a time clock switch, not shown, is 9 enclosed within a suitable waterproof box F which is secured to one side of the base casing 1' immediately below the floor casting 2 of the stereopticonapparatus support. lVhat Iclaim is: r

1. In combination with a projector screen, an incandescent lamp illuminated border arranged on the marginal surface of said screen, a flasher for controlling said incandescentlamp border, an automaticstereopticon projector "focussed on said screen, and means for simultaneously controlling the operation of said flasher and said stereopticon projector. V j

2. In combination with an advertising apparatus of the automatic stereopticon projector type, including means for driving sa1d apparatus, aprojector screen on which said apparatus is focussed, a series of T110311: descentlamps arranged to provide an illuminated border on a marginal portion of the surface of said screen, electric circuits connecting said series of incandescent. lamps with said apparatus, and means for flashing alternate lamps of said series comprising a.

operatively condriving sa1d apranged to provide an illuminated border on a marginal portion of the surface of said screen, an automatic stereopticon projection apparatus adjustably mounted to project upon said screen, a housing for said projector apparatus, motor operated means for intermittently driving and locking said project-or apparatus enclosed Within said housing, an electric circuit flasher mounted Within said housing and connected to be continuously drivenby said motor operated means, and an electric circuit connecting said flasher and said series of incandescent lamps.

4. In combination with a stereopticon projection apparatus, a supporting frame on which said apparatus is mounted, a ventilated flooring on which said supporting frame is mounted, said flooring comprising a plurality of staggered spaced, overlapping, supporting members, vertical spacing members connecting said supporting members, and a housing enclosing said supporting frame and said stereopticon apparatus secured to said ventilated flooring.

5. In combination With a stereopticon projection apparatus, a tiltable support on which said apparatus ismounted, said support comprising a base casting, a ventilated flooring casting adjustably mounted on said base, said flooring casting consisting of vertically spaced supporting portions and intermediate spacing portions extending at substantially right angles to said support,-

ing portions, and a housing enclosing said apparatus secured to one of the spacing portions of said flooring casting.

In testimony whereof I aflix my signature.
